Mine has an intermittent noise in the right earpiece as well on high gain only. Seems to go away if I unplug the RCAs. I discovered today that I can have the RCA cables not plugged into anything but the DX3 (just hanging loose from the back not connected to any speakers, ect.) and I'll get the same intermittent noise on high gain.
I had the same thing. After several plugging of the power adapter and resetting it to the factory settings, the processor started working normally. But after that, it turned out that the right headphone output channel is not working well. There was a strong hiss in the right earpiece. When the +9 db mode was turned on, a constant voltage was generally output to the right earpiece. Left earphone and line-out worked fine.
I have experienced noise from the right speaker and was surprised as this has never happened before.
The noise would come and go, while playing in exclusive WASAPI mode, we are talking pure DAC usage.
I was able to pinpoint the problem.
My Volume mixer is always muted for the system sounds and under sound I have selected 'No Sounds'.
When I changed, personalization settings, background etc. I didn't notice that this change activated a sound scheme for windows sounds.
Of course window sounds didn't play as I have those muted under volume mixer.
However, the interference was created, probably crappy drivers.
The moment I changed the sound theme to 'No Sound' the interference stopped.
Tell me please where did you buy Elna Silmic II?The basic mod is almost done. Still waiting for a few parts for the LPF hence no sound otherwise the unit is functional 100% with stock power supply.
audiophonics.fr ; search for ELNA SILMIC II.Tell me please where did you buy Elna Silmic II?
It's really quite easy. Use low gain until you max it out, and then go high gain. You should not need high gain at all times if you listen at "normal" listening levels I hardly ever had to switch gain mode.Hi i have the dx3 pro and hd650.
Will high gain mode drive these better? I see it gives 123 mw while low gain mode gives 14 mw. Should it affect the audio quality of the HD650?
I'd only switch to high gain if I wanted to get deaf.Hi i have the dx3 pro and hd650.

use low gain unless is not loud enough to youHi i have the dx3 pro and hd650.

I bought this via Massdrop.
Wish me luck!
Nice work. I was surprise you did not replace the cap for the power supply of the analog output . The caps next to the 2 opamp and the caps at the output of the 2 switching ic output for the +/- 10V.The basic mod is almost done. Still waiting for a few parts for the LPF hence no sound otherwise the unit is functional 100% with stock power supply.
Will leave the unit run over night to see whether there's any stability problem.

I don't really like ceramic smd caps for decoupling the opamps.
It all depends on Windows setting.Can someone explain how to configure DX3 PRO in windows 10?
I can not bypass windows volume control.
And why this dac does not change sample rate on display according to sample rate of the music file (it is always 44.1)?
Thank you
